=== RC and Servo Setup ===

+

+

Ardupilot hast just recently added new way which allows to configure the RC channel and the servo behaviour independently. QGC has not included this yet in the RC calibration procedure. Therefore **you have to check the correct servo behavior for RC and autopilot: BOTH!!!** It is possible that RC works in the right direction but autopilot steers in the opposite direction. This was the reason for the first Ardupilot flight crash. ​
